The development and application of a framework that captures main characteristics of learning in nature--the Field Trip in Natural Environments (FiNE) framework--is the main outcome of this study that followed up 22 daily field trips of 4-6th grade students to nature parks. The theoretical and practical framework, which was developed based on the research literature and the data collected, allows systematic analysis of various phases of the field trip: preparation, pedagogy, activity and outcomes. The FiNE framework incorporates multiple views of the researchers and participants and examines the pedagogy employed and the outcomes as reported by the participating students. The employment of the framework indicates limited preparation and the use of traditional pedagogies and highlights the importance of social interactions and physical and learning activity. The FiNE framework provides researchers with a plausible scheme to assess various components of field trips to nature and to elucidate possible outcomes of such experiences.
